Yes, it looks like you need to keep the data around for as long as the
pixbuf. The documentation for the underlying structure does seem to
suggest that we could change it, by taking a copy (maybe inefficiently)
and supplying a callback to delete it:
http://developer.gnome.org/doc/API/2.0/gdk-pixbuf/gdk-pixbuf-creating.html#gdk-pixbuf-new-from-data

But I think it's too late for that. If you submit a patch then we can
consider it for the next API break.
